Abstract
Antimony selenide (Sb2Se3) films were deposited by chemical bath deposition on glass substrates. Deposited films were characterized by X-ray diffraction, scanning electron microscopy and UV–vis–NIR spectroscopy. X-ray analysis of these films confirms an orthorhombic structure. Evaluation of band gap from optical spectra shows absorption due to indirect transition occurring at 1.16eV. For the first time, optical properties including refractive index, extinction coefficient, optical conductivity, reflectivity, absorption coefficient and energy-loss spectrum were calculated by a self-consistent approach using the Wien2k code.
